  1. Investigation Myths and Facts November 29, 2011 IOT Security: Caroline Drum Bradley

  2. About IOT Security • IOT provides computer support for approximately 34,000 state workers and contractors • Handling investigation requests is just part of what we do • Most common investigation requests involve employee discipline, public record request and litigation requests • IOT Security receives around four requests per week, these vary in size and complexity. • IOT Security also proactively notifies agencies of issues that often lead to investigations due to malware and other suspicious activity. • IOT Security cannot perform criminal or forensic investigations

  3. Myths • Every Email Sent or Received can be recovered • Actual Computer Activity can be measured • Network Login and Logout times are available (indefinitely) • Internet Activity and time spent on a particular page can be determined • IOT can identify all data lost in a security breeches and fix it so no reporting is required.

  4. Facts • IOT can provide point in time back-ups of email • Computer Activity can not be directly measured • Logs of Login and Logout times to the network are overwritten quickly • Internet Activity history is stored for 8 weeks • The most common Security Breech involve the loss of equipment – laptops or USB sticks

  5. Email • Email can be restored from point in time backups for the previous 4 quarter and year end from 2006 on. Current email box contents can also be provided • Email needs to be restored by user, a specific topic or message can not be searched for • Email must be reviewed and searched by requesting agency, search terms may need to be adjusted and sensitive data may need to be redacted. • There is a charge for restores based on time periods requested and number of people.

  6. Computer Activity • Computer logs if available do not actually record all activity of users. • Various information can be pieced together to determine if individual is performing required duties. • Email, internet, application logs (if applicable) and cell phone logs can be examined, depending on investigation needs. • Unlike Internet reports and mailbox provision, IOT can do very little to help with time abuse from a policy or technical standpoint

  7. Login and Logout Times • Network logs have limited storage and are frequently overwritten. • Users do not always log off the network daily • Application logs can sometimes provide more accurate data. • Generally login and logout times cannot take the place of overall good management.

  8. Internet History • Internet history is available for the previous 8 weeks. • Internet activity for a user while not on the state network is not captured at this time. • Internet activity consists of websites the user visited including the pop-ups and ads contained on a webpage. • Internet activity needs to be reviewed with knowledge of individual’s job requirements. • Keep in mind that internet should be thought of as a business tool.

  9. Security Breeches • Most security breeches occur when computer equipment of external USB drives, tapes or CDs are lost. • Management of data and its location is the best prevention of breeches. • Users should know what type of data is stored on their computer or external media. IOT cannot determine content once the item is gone. • Encryption should be used to protect data on portable devices and sensitive data should be stored on network drives rather than on local computer drives.

  10. Miscellaneous • Email encryption is available • Computer tracking is available for most computers • Data Loss Prevention product is in place to help better manage data storage and transmission.
